Asserting Visual Elements and Visualizing the Result with Appium Ruby
The Importance of Visual Elements: Software applications today are highly dependent on visual components for user experience. User interfaces (UI) and user experience (UX) design play a critical role in the success of the application.
The Role of Testing: Testing is an essential part of the software development process to ensure that visual components meet expectations.
Definition of Visual Tests
What is Visual Testing: Visual testing is the process of checking whether the visual elements within the application (buttons, menus, images, etc.) are displayed correctly.
Objective: To improve the user experience, detect bugs early and ensure the consistency of the application.
Types of Visual Tests
Screenshot Based Tests: Taking screenshots and comparing them with expected results.
Visual Component Checks: Checking whether the components (buttons, form fields, etc.) are placed correctly.
User Interface (UI) Tests: Testing the interactive components of the user interface.
Detection of Visual Errors: Manual detection of visual errors can be time-consuming. Automated testing tools can help in this process.
Screen Size and Resolution Differences: Testing on different screen sizes and resolutions is essential to ensure visual consistency.
The basic steps for visual testing are as follows;
1. Read Reference Image
2. Take Screenshot
3. Compare Images
4. Save Visualized Result
5. Asssert Similarity Score
I read my png format file with binary code.
I read the screen image of the page I am looking for a visual match with binary code

Now I can search for the reference image in the full image.
This will give us the option to obtain it visually if the image match is successful.
We can now write it to a file of our choice.
We can then assert the result based on the score value we set to express the similarity more concretely.
Marking of visual data will be in the red box.
For visual options to be active commands in sequence.
appium plugin install images
appium --use-plugins=images
I hope it was useful.
